Push on Android shows: "This site has been updated in the backgroud"

hi all,

I integrated webpushr in a react project.
Sending push notification work well on desktop chrome. The message returned has the correct title body and even logo.

But, for some reason, this is not the case when pushing to an android device (with chrome browser of course)
the device get the notification as follows:

This site has been updated in the background.

any advice would be appreciated.

This usually happens when there is a service worker conflict. Only one service worker file can be activated per domain.
